Definitions

  • the present invention relates to a yarn withdrawal nozzle for an open-end rotor spinning device having an end face, a nozzle bore and a funnel-shaped Garnumlenk Chemistry connecting the end face and the nozzle bore, the end face adjoining the Garnumlenk materials and wherein the end face and the Garnumlenk materials form an effective diameter of the thread take-off.
  • Thread withdrawal nozzles have become known in the prior art in open-end rotor spinning devices in many designs. Such thread take-off nozzles have the task of redirecting the spun yarn during removal from the spinning device and to give the withdrawn yarn a false twist.
  • the true twist of the yarn is introduced predominantly between the yarn draw-off nozzle and the draw-off device in the freshly spun yarn, but does not propagate sufficiently into the rotor groove.
  • the yarn draw-off nozzle must thus enable the reproduction of the genuine yarn twist into the rotor groove on the one hand and on the other hand give the yarn as much as possible an additional false twist.
  • DE 199 01 147 B4 considers such an edge to be disadvantageous, since a high surface pressure is generated during the crank-like rotation of the thread over this edge.
  • DE 199 01 147 B4 proposes to form the yarn deflection surface with a maximum radius of curvature of 3 mm.
  • the end face should connect tangentially and form a yarn supporting the guide surface, which is considered advantageous.
  • the object of the present invention is to propose a yarn draw-off nozzle which avoids overheating of the draw-off nozzle and enables a good propagation of the yarn twist into the rotor groove.
  • a yarn withdrawal nozzle for an open-end rotor spinning device has an end face, a nozzle bore and a funnel-shaped yarn deflection surface connecting the end face and the nozzle bore.
  • the end face adjoins the Garnumlenk procedures, wherein the end face and the Garnumlenk components form an effective diameter of the thread take-off.
  • the end face and the yarn deflection surface form an input-side region of the yarn draw-off nozzle, while the nozzle bore forms an exit-side region of the yarn draw-off nozzle.
  • the nozzle bore usually has a constant inner cross section over the length or the axial extent of the yarn draw-off nozzle, while the yarn deflection surface reduces over the axial extent of the yarn draw-off nozzle. having inner cross-section.
  • the end face is oriented substantially radially to the nozzle bore, but may also have a curved or radially outwardly conically sloping course.
  • the effective diameter of the yarn withdrawal nozzle is less than 8 mm and the Garnumlenk materials has a radius of curvature of less than 2.5 mm.
  • the present invention has found that in addition to the actual Garnumlenk procedures and the end face has a significant influence on the rotation propagation.
  • the present yarn withdrawal nozzle not only the radius of the Garnumlenk materials, but at the same time the entire end face is substantially reduced, so that the overall result is a very small effective diameter.
  • the combination of a small radius of Garnumlenk procedures with the small effective diameter or the smaller end face causes a change in the ratio of false rotations to actual rotations, so that much more real rotations arrive in the rotor groove.
  • the overall rotation of the thread towards the rotor groove can thus be increased and thus a very good spinning stability can be achieved.
  • the heat development is reduced by the short Garnumlenk materials and subtracted the thread gentler.
  • a head diameter of the yarn draw-off nozzle is less than 10 mm.
  • the head diameter is defined as the largest outer diameter of the yarn withdrawal nozzle.
  • the head diameter can also be equal to the effective diameter; As a rule, however, the head diameter is slightly larger than the effective diameter, so that radially outward adjoins the end face another, annular surface, which, however, is not usually in contact with the thread. Due to the very small outer diameter of the yarn withdrawal nozzle, the frictional heat generated by the circled over the thread take-off yarn can be dissipated much better, since the heat radiation of the part of the rotor housing in which the yarn take-off is stored, is not hindered by the Fadenabzugsdüse.
  • the Garnumlenk materials tangentially adjoins the end face.
  • no edges are arranged between the Garnumlenk materials and the end face.
  • the propagation of the true yarn twist in the rotor groove is thereby further improved.
  • the contact force of the thread is reduced at the transition from the end face to Garnumlenk materials, so that less friction occurs and thus the temperature stress of the thread is reduced.
  • the Garnumlenk materials tangentially connects to the nozzle bore.
  • Garnumlenk Materials in particular radially arranged notches having. These stimulate the thread in a manner known per se to rotate about its longitudinal axis and thereby bring a false twist into the thread in a comparatively thread-saving manner.

  • the notch thus extends into the nozzle bore into it and is characterized comparatively steep.
  • the thread can run better in the notches and thus experiences a particularly significant change in length in the circumferential yarn leg.
  • the change in length and therefore also the thread tension tip produced by the notch are greater, the steeper the notch. Due to the steeper outlet of the notches in the nozzle bore while a smoother transition when reaching and leaving the notch is achieved at the same time, so that negative influences of the notches on the yarn quality can be avoided.
